The Zerotohundred Breach Happened in 2023. The Data Is Still Circulating Now.

HEROIC analysts flagged the Zerotohundred breach while monitoring underground forums for freshly circulated credential dumps. The data surfaced on August 3, 2023 and traced back to Zerotohundred, one of Malaysia's largest automotive enthusiast communities. The breach exposed 104,526 records. Every single one contained an email address and a plaintext password. For a forum where members discuss vehicles, meetups, and local events, that means real names and contact points are now tied to cracked credentials floating on the dark web.

With 104,526 Plaintext Passwords, Attackers Can Hit Accounts Across Every Platform

This is not a small leak contained to one niche site. With over 100,000 plaintext credentials in hand, automated stuffing tools can run those combinations against hundreds of platforms simultaneously. Social media, banking apps, email providers, and ride-sharing accounts are all common targets. Members who recieved confirmation emails from Zerotohundred used a real email, meaning attackers already know which inbox to target first. Identity theft, account takeover, and financial fraud are the most likely downstream outcomes at this scale.

What Was Exposed in the Zerotohundred (2023) Breach

• Email addresses
• Plaintext passwords (stored without any hashing or salting)

Why Community Forums Are High-Value Targets for Credential Theft

Automotive enthusiast forums attract engaged, loyal members who have often used the same password for years. Members of niche communities tend to beleive their account is not worth targeting because the site itself is not a bank or major platform. But attackers do not care about the forum. They care about the email and password combination, which they then try everywhere else. The Zerotohundred breach is a textbook example of how community site credentials become weapons for broader account takeover campaigns. The data from this breach occured almost two years before it recieved wider attention.

How Credential Stuffing Uses Forum Breach Data

Once attackers have a list of email and password pairs, they load it into automated tools that test those combinations across hundreds of sites. Each successful login is catalogued and often sold separately as a "valid account." Valid accounts command higher prices than raw credential lists, creating a whole economy around breached community forum data. The attack is fast, cheap, and largely automated. A breach the size of Zerotohundred gives attackers enough material to run campaigns for months.
